WARNING
!
!
Cleaning agents and paint ingredients may be flam-
mable and/or explosive, or dangerous to inhale. Be
sure to use adequate ventilation, and appropriate
safety clothing. (gloves, safety glasses, respiration,
etc.)
13.2.10 Bottom Paint Preparation Warning
Do not
use any sanding, sandblasting or other abrasive
t
reparation of the bottom, as this will void your hull blis-
tering warranty. See the warranty information in Chapter
3 of this manual.
Important: Do not paint the zinc anodes (connected to the
boat’s bonding system) on the outside of the transom.
3.2.11 Bottom Painting
Choose a bottom paint system that suits the environment
in your area. Follow the procedure recommended by the
manufacturer of the paint, while making sure not to void
the Mainship Hull Blistering Warranty. The procedure for
preparing and painting the bottom varies between paint
manufacturers, but should always include dewaxing,
etching and sometimes priming of the surface.
13.2.12 Epoxy Barrier Coat
Sanding of the gel coat bottom surface will be permit-
ted should a customer wish to have epoxy barrier
coat applied to the hull, (example Interlux Interprotect
1000, 2000, West System or VCTar). This will not
void the Five-Year Blister Warranty. Mainship refers to
epoxy barrier coatings as mentioned above, not epoxy
primer paints. If an epoxy barrier coat is applied to a
Mainship vessel, it must be registered with the Warranty
Department prior to application of the product. If the
dealer applies bottom paint only, sanding
will not
be
t
allowed and the no sanding system must be used.
13.3 Interior
You can usually clean the surfaces of these components
with a mild cleaner such as Fantastic. Avoid using harsh
or abrasive cleaners. Use approved marine sanitary
treatment chemicals to control the odor in the toilet and
holding tank.
13.3.2 Walls
The wood used in your boat is treated at the factory with
a multi-coat finish process. To maintain the finish, use a
good grade of furniture polish.
13.3.4 Bilges
The bilges are finished with a high quality gelcoat which
is easy to keep clean. Several brands of bilge clean-
ers will dissolve dirt and grime, but will not harm the
environment when pumped overboard. If you keep the
bilge clean, it is much easier to identify leaks or other
problems if they should develop.
Important: The Federal Water Pollution Control Act prohibits
the discharge of oil or oily waste into or upon navigable waters
in the United States. Violators are subject to a penalty.
13.3.5 Shower Sump
The showers drain into contained Sump which keep hair,
soap, scum, and bacteria from building up in the bilge
and developing an odor. The Sump consists of a plastic
box, a pump, and an automatic float switch. A detailed
instruction on cleaning the shower sump can be found
in the Sanitary Systems Chapter 10. This describes the
function more thoroughly.
Important: Periodically open the sump box and clean out the
buildup of hair and scum to prevent eventual clogging of the
pump.
13.4 Mechanical Systems and
Components
Refer to the manuals supplied by the boat component
manufacturers for their recommended periodic mainte-
nance. The manuals may indicate maintenance require-
ment, in addition to, the minimum maintenance tasks
listed in the following charts.
Note: In case of conflicts between the maintenance informa-
tion in this manual and the manuals supplied by the equipment
manufacturer, the equipment manuals take precedence.
13.4.1 Engine Oil
See engine operating manual for recommended oils and
correct procedures for checking and replenishing oil.
